, BLASTING CERTIFICATE 2026/2027 QUESTIONS WITH 100% PASSED ANSWERS!!
SECTION 1: LICENSING, RESPONSIBILITIES & REGULATORY COMPLIANCE
Q1.
A newly certified blaster is assigned as the blaster-in-charge for a surface coal mine shot. Before any explosives are
brought to the bench, a state inspector asks who holds ultimate responsibility for ensuring the blast is designed and
executed to prevent injury and property damage. Which answer is correct under federal and typical state standards?
A. The drill operator who logs the borehole depths.
B. The certified blaster who is designated blaster-in-charge for that shot.
C. Any member of the blasting crew who has completed general mine orientation.
D. The equipment manufacturer who supplied the initiation system.
Correct Answer: B
Rationale:
Regulations place direct responsibility for the safe use of explosives on the certified blaster who is in charge of the shot. Crew
members work under that person's direction; manufacturers and drillers do not assume the regulatory duty of the blaster-in-charge.
Q2.
During a compliance audit the inspector asks whether a person who only assists with stemming and never handles
detonators needs to be a certified blaster. What is the correct regulatory position?
A. Every person who steps onto the blast pattern must hold a full blaster certificate.
B. Uncertified helpers may assist under the direct supervision and direction of a certified blaster, but may not take
independent control of the shot.
C. Helpers may design and fire shots as long as a certified blaster is somewhere on the mine property.
D. Certification is required only for underground work, not surface work.
Correct Answer: B
Rationale:
Federal standards allow non-certified personnel to assist when they receive direction and on-the-job training from a certified blaster.
Independent control of loading, timing, or firing remains restricted to certified blasters.
Q3.
A blaster discovers that the magazine inventory log has not been updated for three days even though product was
removed for a shot. What is the immediate professional obligation?
A. Ignore the discrepancy because the shot already occurred without incident.
B. Correct the inventory records at once, investigate the discrepancy, and report any unresolved shortage according to
company and regulatory procedures.
C. Wait until the next monthly audit to reconcile the numbers.
D. Discard the old log and start a new one without noting the gap.
Correct Answer: B
Rationale:
Accurate, timely inventory is a core regulatory and security requirement. Discrepancies must be investigated and documented
promptly; unresolved shortages may require notification to authorities.
